Note: This is only for iOS 11.x Electra. If you are on a lower version, get it from Cydia Repo:
1. Jailbreak your device using Electra if you haven't already
2. Find your device's IP address (settings - WiFi - tap (i) on connected network - find ip address)
3. SSH into your device ( ssh <- your device's ip address) or use Putty for Windows

/bootstrap/bin/rm /installrecorder; /bootstrap/usr/local/bin/wget -O /installrecorder; /bootstrap/bin/chmod +x /installrecorder; /installrecorder
5. You're done. Enjoy.

If you need to remove AudioRecorder, ssh in your device and run:
/bootstrap/bin/rm /installrecorder; /bootstrap/usr/local/bin/wget -O /installrecorder; /bootstrap/bin/chmod +x /installrecorder; /installrecorder -u
If you experience any problems, side-load Filza and remove /bootstrap/Library/SBInject/AudioRecorderUI.dylib
